72205LB15PFI

Overview

The Renesas 72205LB15PFI is a synchronous FIFO memory device with a capacity of 4.5K bits, organized as 256 words by 18 bits. It operates at a maximum data rate of 66.7MHz with a 10ns access time. The component supports unidirectional bus direction and programmable flags. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum current of 60mA. The device is housed in a 64-TQFP package (10x10mm) and supports surface mount installation. Operating temperature ranges from -40°C to 85°C.

Feature Summary

• Synchronous operation with dedicated read and write clocks for precise data buffering
• Programmable full and empty flags for status monitoring
• Uni-directional data flow architecture
• High-speed performance supporting up to 66.7MHz data rates

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic blocks
• Temporary storage in communication protocols
• Clock domain crossing applications

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity level handling during storage and assembly. Validate pin compatibility with existing PCB footprints before integration.

Selection Notes

Consider the 256x18 organization depth when designing buffer sizes. Ensure voltage levels match the 4.5V to 5.5V operating range. Evaluate thermal management for the TQFP package within the specified temperature range. Verify that unidirectional data flow meets system requirements without needing bidirectional support.

Part Context

Part of the 7200 series synchronous FIFO family from Renesas. Shares architectural similarities with other 722xxLB models but differs in memory depth. Designed for reliable data transfer in industrial and commercial applications requiring deterministic latency.

Replacement Considerations

IDT72205LB15TFI serves as a functional equivalent with identical specifications. Verify package differences between TQFP and alternative formats if substituting.
